Naming and creating variables

Variables in PowerShell are preceded by the dollar symbol ($), for example:

$MyVariable

The name of a variable may contain numbers, letters, and underscores. For example, each of the following is a valid name:

$123 
$x 
$my_variable 
$variable 
$varIABle 
$Path_To_File 

Variables are frequently written in either camel case or Pascal case. For example:

• $myVariable is camel case
• $MyVariable is Pascal case

PowerShell does not enforce a naming convention, nor does it consistently use a convention in the automatic variables.

One of the most commonly accepted practices is that variables used as parameters must use Pascal case. Variables used only within a script or a function must use camel case.

I suggest making your variable names meaningful so that when you revisit your script after a long break, you can identify its purpose. I recommend choosing and maintaining a consistent style in your own code...
